THE 4-MEMBER SQUARE SCHEME IN CYCLIC VOLTAMMETRY - GENERAL-SOLUTION FOR NERNSTIAN ELECTRON TRANSFERS

A general solution of the four-member square scheme under cyclic volta mmetric conditions is presented. The diffusional problem is converted into a system of integral equations, which can be solved numerically, giving 'individual' currents. The heterogeneous electron transfer step s are assumed to be nernstian, while no limitations on the magnitude o f the kinetic constants of the homogeneous chemical reactions are impo sed.
